Here's the spark plugs they look like they need to be replaced.

 

Two of those are definitely done for!

 

Yes the check engine light was flashing for sure and here are the results of the compression test If i did it right

 

Compression is fine, change those plugs though

 

Best one to get?

 

I would go a step colder on the plugs. What plugs are those exactly?

 

They are Bosch platinum but don't mind putting the iridiums just not sure which ones

 

I would be sure it is a 9 or a 10 heat range plug. Then, come down on the spark gap a few thousandths as well.

What brand you get, is up to you. Iridium are long lasting, but can be very fragile when gapping them.

 

This the one that boostedka is using NGK BKR7E-11

 

I'm not sure how consistent the companies are with their heat ranges, but that plug he is using is a hotter plug than you are running per the 'heat range' claimed by the makers. The gap is so extreme on the worn plugs, that you should maybe just grab the same set again, and verify your gap across all of them, and get a baseline.

 

I'll just go with the NGK for my truck specifically and tell them I want a heat range lower

 

or do that

 

I'm running those plugs.

Edit : running one range hotter and gap around .03" to .026"

 

I went with what AutoZone came up with and it was BKR5EIX-11

 

Exactly, and I'm running one range cooler because boost.

 

Here's what I get now

 

You cleared the codes first before going for the test drive?

 

That was just from idle in the driveway I'll reset the codes and go for a test

 

If you have a lean code while idling, go easy on the test drive.

 

I would like to know your fuel pressure too. The lean code is a part of the puzzle now lol
